This paper presents a conversational interface that uses the speech recognition and synthesis and animation abilities of two Microsoft software agents in order to assure a more natural and efficient interface with an autonomous robot. The interface is used in the robotics educational process. The basic commands to be given by voice (back, right, etc.) and the control of the agents are implemented in Visual Basic. More complex control programs can be implemented and tested in Matlab and after that executed with a simple voice command. This program is used as a part of an integrated educational strategy in autonomous robotics and was evaluated by a group of students. First experimental results related to the use of this conversational interface compared to traditional robot simulation environments and control of real robots are presented in this paper with related discussions.
The previously developed Predictive Pole Placement (PPP) controller is modified to give enhanced numerical and stability properties by embedding the method in a linear-quadratic formulation to give a linear-quadratic ...

This paper builds on the OSNR model in "Power control for OSNR optimization in optical networks: A noncooperative game approach." (Pavel, 2004) and studies the optimization problem of optical signal to noise ratio (OSNR) in the case of single point-to-point links. An m-player noncooperative game is formulated and the cost function for each channel is introduced, with differentiated prices. The status of the link, i.e. such that the total input optical power will not exceed the link's capacity, is considered in the cost function. Conditions for existence and uniqueness of the Nash equilibrium solution are given. Some strategies for dynamic price setting are also discussed, in the context of dynamic channel-add.
This paper developed an adaptive estimation method to estimate unknown disturbances in a class of nonminimum phase nonlinear MIMO systems. The unknown disturbances are generated by an unknown linear exosystem. The fre...

We provide an overview of the DAME project, and a discussion of the progress made to date on the development of a distributed aeroengine diagnosis environment as a proof of concept demonstration for grid computing. We discuss the development of a demonstration diagnosis workbench system for this complex, data intensive, diagnosis application that must be operated as a distributed 'virtual organisation'. We describe the core diagnosis applications that have been implemented as grid services, and explain how these services are being deployed within the overall diagnosis process

Embedded controlsystems are becoming ubiquitous in control applications. They combine the properties of computer embedded system with newly designed complex controllers where flexible, safe and reconfigurable operations are required. The aim of this paper is to grasp the main features of these systems, analyse the main problems and present some solutions already developed by the authors. A new concept on the control kernel of an application is also introduced and some conclusions are drafted.
